Theremidi Orchestra (TO) is an audiovisual DIY community initiated by participants of the Theremini and Teremidi physical interface workshop, organised by Ljudmila – Ljubljana Digital Media Lab in May, 2011. Rather than a subject, TO is a verb, an ongoing workshop of noise and drone production. This hands-on electro noise ensemble exists in the present continuous, while referring to the history of electronic music. TO has a DIY/DIWO approach in making music and sound experiments, developing its own instruments based on open-source electronic circuits, with CC licences. Currently TO consists of nine active members, coming from different professional backgrounds. Thus far, the orchestra performed, exhibited and held workshops at over thirty festivals and exhibitions mostly in Europe e.g. Piksel Festival in Bergen Norway; LiWoLi Festival in Linz, Austria; PoolLoop in Zürich, Switzerland; U3: Triennial of Contemporary Art, Museum of Contemporary Art in Ljubljana, Slovenia, and most recently at Eyebeam / CT-SWaM, New York.
